Тогда надо добавить еще вот что;

  private float curAlt = 300.0f;
  private float curSpd = 50.0f;

  
  class Interpolater extends InterpolateRef 
  {
    public boolean tick() {
      resetYPRmodifier();
      float v = ((G_37)aircraft()).fSightCurSpeed;
      float h = ((G_37)aircraft()).fSightCurAltitude;
      curAlt = (19.0f*curAlt+h)/20.0f;
      curSpd = (19.0f*curSpd+v)/20.0f;
      mesh.chunkSetAngles("zScaleKM", 0.04f*curAlt, 0.0f, 0.0f);
      mesh.chunkSetAngles("zScaleM", 0.36f*curAlt, 0.0f, 0.0f);
      mesh.chunkSetAngles("zScaleKMH", -0.8f*(curSpd-50.0f), 0.0f, 0.0f);
      float m300 = 0.5f*(float)Math.tan(Math.atan( (300.0f/3.6f)*(Math.sqrt(2.0f*curAlt/Atmosphere.g()))/(curAlt) ));
      float m = (float)Math.tan(Math.atan( (curSpd/3.6f)*(Math.sqrt(2.0f*curAlt/Atmosphere.g()))/(curAlt) ));
      xyz[0] = -0.0005f*curAlt;
      xyz[1] = -1.0f*(m300 - m);
      mesh.chunkSetLocate("zScaleCurve", xyz, ypr);

      if (bEntered)
      {
    	  float tan = aircraft().FM.Or.getTangage();
    	  if (tan > 5f)
    		  tan = 5f;
    	  else if (tan < -5f)
    		  tan = -5f;
    	  mesh.chunkSetAngles("BlackBox", 0.0f, 0f, tan);
    	  HookPilot hook = HookPilot.cur();
          hook.setInstantOrient(aAim, tAim-tan, 0f);
      }
      
      return true;
    }
  }
  
    public void reflectWorldToInstruments ( float delta ) 
	{
		if(bEntered) {
		  mesh.chunkVisible("BlackBox", true);
		  mesh.chunkVisible("zReticle", true);
		  mesh.chunkVisible("zScaleCurve", true);
		  mesh.chunkVisible("zScaleM", true);
		  mesh.chunkVisible("zScaleKM", true);
		  mesh.chunkVisible("zScaleKMH", true);
		}else {
		  mesh.chunkVisible("BlackBox", false);
		  mesh.chunkVisible("zReticle", false);
		  mesh.chunkVisible("zScaleCurve", false);
		  mesh.chunkVisible("zScaleM", false);
		  mesh.chunkVisible("zScaleKM", false);
		  mesh.chunkVisible("zScaleKMH", false);
		}
	}

И в класс самолета добавить если нет:

	public float fSightCurAltitude = 300.0f; // 300 - 5000 m
	public float fSightCurSpeed = 50.0f; // 50 - 350 km/h

	}

	public void typeBomberUpdate(float dt)
	{

		}
	}

	public void typeBomberReplicateToNet(NetMsgGuaranted out)

Весь код под версию 4.13, для 4.12 возможно потребуется поправить.
